It sounds like you have already made up your mind, and actually only wanted to hear thoughts that agreed with the conclusion you have already decided on? I had a race car shipped from Ontario to Oregon for $1500. What a rusty POS that was! Lesson learned. It was a rail company that did it. I remember that shipping inside canada was even cheaper. If you're happy with the van and don't want to look any more then I guess there is only one outcome.
Not so much really, just that shipping/travel isn't really an option. Buying a car from Ontario was kind of a bad idea honestly as that is one of the most heavily salted areas in Canada. This is Canada, not the us. I live on an island(Newfoundland) as far east in Canada as you can get, we have our own time zone. Shipping a car averages 3-4k period from quotes on our local car group on Facebook from users who have shipped in supras and other foreign vehicles from BC and Alberta.
As far as vehicles here go, its cheaper to look at vehicles that people have already driven from areas with no salt. Be it Alberta, Florida or BC, where this one is from ...
To the contrary I was honestly looking for opinions to deter me from purchasing the van, I just dont agree with the alternative points you made. Rust wasnt a concern on this one as it was one of the cleanest I've viewed yet. This isnt going to be a show vehicle, It would be seeing good use and likely winter driving where it will see salt anyways.
